Babe Bee is always clear anodized or silver aluminum.
They have a 5 cc tank with no tubes sticking out, and the backplate has either one filler nipple and a vent, or two nipples. Since fill/vent is topside, well, it normally only runs with the backplate upright.
Black Widows and Golden Bee's have their obvious color. However, they hold 8 CC's, and the backplate has no vent/fill.
Instead the vent/fill tubes are on the tank. One from topside going down to just above the inside/bottom of the tank. The other enters the tank from below, and stops just inside/below the top of the tank. Basically, the tubes are set up like a wedge tank.
As long as the fuel pickup tube makes it to the outside, and low on the tank, the BW, GB backplate could possibly be in any of the four possible positions (needle upright, to either side, or down).
For a while, I ran my Golden Bee sideways with the cylinder out starboard, and the needle to inboard. No upside down landings were going to take out my glowplug or needle!
The tank tubes still went up and down.
Oh, and those fill/vent tubes...ISTR they fall to one side or the other of the venturi. You want them inboard so they don't syphon fuel through the whole run. If they are outboard, they are syphoning-out fuel longer.
